High-bandwidth Digital Content Protection (HDCP) is required for Blu-ray movies in VIP airplanes. This is necessary to comply with Digital Rights Management (DRM) regulations.

Here are notes on how the following Cabin Management System companies are handling HDCP on their system backbones.

Flight Display Systems (Fly HD, Select CMS)
Flight Display Systems uses HDMI to broadcast true 1080p video throughout the aircraft cabin. The HDMI signals are transmitted (uncompressed) via Cat5 Ethernet cable. That allows the HDCP to function as intended with no modifications. This is the easiest method for true HD video in the aircraft cabin.

Heads Up Technologies (Citation Ten CMS)

Honeywell (Ovation Select)

Rockwell Collins (Venue)
Rockwell Collins also uses HDMI, but their system is limited to 720p. Many Venue installations also use HD-SDI to easily transmit the HD video on a single coaxial cable. The problem with HD-SDI is that it does not allow for HDCP. So Rockwell Collins has designed a closed loop solution involving communication via RS-232. This makes a handshake between the Venue High Definition Audio/Video Distributor (HDAV) and an LCD monitor. A command is sent every few seconds by the HDAV to poll the HD monitor handler via RS-232. If a response is not received within ten seconds, the HDAV from Rockwell Collins with disable the HD-SDI video output. A black pattern is shown instead.
** Any third-party LCD or plasma monitors working with Rockwell Collins Venue system must have the proprietary Rockwell Collins protocol implemented.
